CC -!- FUNCTION: Reducing polyketide synthase; part of the gene cluster that
CC mediates the biosynthesis of fusarielins F, G and H, decaketide
CC compounds with 5 methylations and a decaline core that act as
CC mycoestrogens as they stimulate growth of MCF-7 breast cancer cells
CC (PubMed:22252016, PubMed:27983606). The initial compound in the pathway
CC is produced by the reducing polyketide synthase FSL1. FSL1 lacks an
CC active enoyl reductase (ER) domain and biosynthesis of fusarielins
CC relies on the trans-acting enoyl reductase FSL5, before it is released
CC through hydrolysis catalyzed by the thioesterase FSL2 (PubMed:22252016,
CC PubMed:27983606). Fusarielins F, G, and H have a C11=C12 cis double
CC bond and is fully reduced between C10 and C11 and between C12 and C13.
CC FSL3 can be involved in the formation of the C11=C12 cis double bond by
CC moving a hypothetical C10=C11 or C12=C13 trans double bond to form
CC prefusarielin (PubMed:27983606). Prefusarielin is oxygenated at C15 and
CC C16 by the cytochrome P450 monooxygenase FSL4, resulting in fusarielin
CC F, which subsequently is epoxidized into fusarielin G by the same
CC enzyme (PubMed:27983606). The final step in the pathway is a reduction
CC of the carboxylic acid moiety to yield fusarielin H via a still
CC undetermined mechanism (PubMed:27983606). {ECO:0000269|PubMed:22252016,
CC ECO:0000269|PubMed:27983606}.
CC -!- COFACTOR:
CC Name=pantetheine 4'-phosphate; Xref=ChEBI:CHEBI:47942;
CC Evidence={ECO:0000250|UniProtKB:Q9Y8A5};
CC Note=Binds 1 phosphopantetheine covalently.
CC {ECO:0000250|UniProtKB:Q9Y8A5};
CC -!- PATHWAY: Secondary metabolite biosynthesis.
CC {ECO:0000269|PubMed:22252016, ECO:0000269|PubMed:27983606}.
CC -!- INDUCTION: Expressed during sexual development (PubMed:16278459). Is
CC not expressed during infection of wheat plants (PubMed:23290226).
CC Expression is positively regulated by the fusarielin biosynthesis
CC cluster-specific transcription factor FSL7, probably via its binding at
CC the 5'-CGGNNNCCG-3' motif present in the promoter of all the cluster
CC genes (PubMed:22252016). {ECO:0000269|PubMed:16278459,
CC ECO:0000269|PubMed:22252016, ECO:0000269|PubMed:23290226}.
CC -!- DOMAIN: Multidomain protein; including a ketosynthase (KS) that
CC catalyzes repeated decarboxylative condensation to elongate the
CC polyketide backbone; a malonyl-CoA:ACP transacylase (MAT) that selects
CC and transfers the extender unit malonyl-CoA; a dehydratase (DH) domain
CC that reduces hydroxyl groups to enoyl groups; a methyltransferase (MET)
CC domain that transfers methyl groups to the growing polyketide; a
CC ketoreductase (KR) domain that catalyzes beta-ketoreduction steps; and
CC an acyl-carrier protein (ACP) that serves as the tether of the growing
CC and completed polyketide via its phosphopantetheinyl arm (Probable).
CC Lacks an active enoyl reductase (ER) domain that reduces enoyl groups
CC to alkyl groups, and biosynthesis of fusarielins relies on the trans-
CC acting enoyl reductase FSL5 (Probable). {ECO:0000305|PubMed:22252016}.
CC -!- DISRUPTION PHENOTYPE: Leads to significant increase in growth
CC (PubMed:16278459). Abolishes the production of fusarielins F, G and H
CC (PubMed:22252016, PubMed:27983606). {ECO:0000269|PubMed:16278459,
CC ECO:0000269|PubMed:22252016, ECO:0000269|PubMed:27983606}.
